Included within castanops by earlier workers (Nelson and Goldman, 1934a; Russell, 1968a; Hall, 1981), but karyotypically (2n=42 – Berry and Baker, 1972; Lee and Baker, 1987) and phylogenetically distinct by mitochondrial DNA analysis (DeWalt, et al., 1993; Demastes et al., 2002); see also Alvarez and Alvarez-Castañeda (1996). Validity of subspecies listed is based on Russell (1968a), who included goldmani and its component taxa within Cratogeomyscastanops.
